简介
Sparse representation has attracted much attention in the field of biometrics, such as face recognition and palmprint recognition. Although the -norm based sparse representation can obtain more sparse solution than the widely used -norm based method, it needs to solve a non-convex optimization problem, which leads to poor robustness in real application. In this paper, we propose a robust -norm sparse representation method with adaptive feature weighting. We derive the adaptive feature weighting method by self-paced learning (SPL), and utilize it to guide the features of -norm sparse representation in the easy-to-hard learning process. Differing from existing SPL methods, feature weighted SPL in our method dynamically evaluates the learning difficulty of each feature rather than sample. For the advantages of the proposed method, it can avoid -norm sparse minimization failing into bad local …
